Hmmm... I didn't even know there was a HS-655+, but it's just a re-branded Plantronics. I use a Plantronics Discovery 665 and I love it. Pretty much the same form factor as the 655 but the color scheme is reversed. It gets rid of the useless (IMO) vibrate function (my phone already vibrates) of the pocket and replaces it with a flashing LED function during incoming calls - good visual notification... especially nice at night in the car! It also comes with a sweet car adapter that charges it and holds it in place for easy access. If you don't have to have the BlackBerry branding on your BT headset, I would recommend the Plantronics 665!
